Abstract Amorphous materials with non-periodic structures are commonly evaluated based on their chemical composition, which is not always the best parameter to evaluate physical properties, and an alternative parameter more suitable for performance e

Light pulses can control magnetism in a material, and the effective creation of magnetic oscillations leads to spintronic devices with higher efficiency. Here, the authors increase the efficiency of magnon excitation by using a material in which orbi

Physical properties of glasses are closely related to their amorphous structures, which can form complex networks depending on the chemical constituents. Here, Onoderaet al. unlock this relationship in a zinc phosphate glass at an atomistic level, wh

Sillén–Aurivillius perovskite Bi4NbO8X (X = Cl, Br) is a promising photocatalyst for water splitting under visible light, as well as a potential ferroelectric material. In this work, we investigate the crystal growth conditions by mainly varying s

A large relative surface area is crucial for high catalytic activity. Monolithic catalysts are important catalytic materials because of minimal self-degradation. Regarding large surface area catalysts, the glass–ceramics (GCs) with high formability

We performed terahertz time-domain spectroscopy and low-frequency Raman scattering on polymethyl methacrylate to investigate the boson peak (BP) which is a universal excitation in glass, and the fracton which is expected to be expressed in polymer gl
